Abstract

The invention discloses an automatic production method of a PCB. The automatic production method comprises the steps of material cutting, film drying at an inner layer, browning, inner-layer board lamination, copper deposition, board electroplating, film drying at an outer layer, gold electroplating, green oil wetting, goldfinger plating, tin spraying and gold deposition. In the step of material opening, a large material is cut to various fine materials by an automatic cutting machine according to specifications, a tip end of a round board is grinded by a round angle grinding machine, the board is placed in an oven for heating after the board is washed and dried by a board washing machine, the board is taken out after cooling and then is labeled as a mark; and in the step of film drying atthe inner layer, the board is placed in a chemical cleaning machine by a carrying device, and the cleaning is completed sequentially by washing, micro etching, high-pressure washing, cycle washing, water suction, strong wind blowing and hot-air secondary drying. The automatic production method is high in automation, the whole PCB production efficiency is high, and the damage to the PCB is low during the production process.

Description

technical field

[0001] The invention relates to the field of automatic production of PCB boards, in particular to a method for automatic production of PCB boards. Background technique

[0002] PCB board is also called printed circuit board, printed circuit board, referred to as printed board, with insulating board as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component holes, fastening holes) , metallized holes, etc.), used to replace the chassis of the previous device electronic components, and realize the interconnection between electronic components, because this board is made by electronic printing, it is called "printed" circuit board ; It is not accurate to call "printed circuit board" as "printed circuit" because there are no "printed components" but only wiring on the printed board.

[0003] In the actual application process of the existing automatic production method of PCB board, the degree of ...
